ROLLER COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 653,367, dated July 10,1900. Application lecl December 13, 1.899. Serial No. 740,167. (Nomodel.)

To a/ZZ whom it may concern:

-Be it known that I, NORMAN. C. STILEs, a citizen of the United States,residing in Watertown, in the county of Jefferson and State of New York,have invented certain new and useful Improvements in Roller Copying-Presses, of which the followingis a specifica- Y tion.

A provement isto enable the work to be done rapidly and in a moreefficient manner by de- 'vices embodying a series of vertically-alinedrollers, over and between which the paper strip is passed, aremovablereel upon which the paper may be Wound, and a cutter for severing thesheets containing the impressions from said strip or web.

Other details of my invention relate to the removable pan or water-tankand other parts, as will hereinafter appear.

In the accompanying drawings,in which like numerals are employed todesignate like parts throughout the several views, Figure 1 is alongitudinal vertical section of the machine. Fig. 2 is an end View,partly in section, illustrating the peculiar kind of cutter employed forsevering sheets from the strip. Fig. 3 is a view, partly in section, ofthe reel on which the strip may be wound after it leaves thecopying-roll. Fig. 4 is a sectional view of the body of thewinding-reel. elevation; and Fig.- 6 is a transverse section of themachine on line :z5-Fig. 5, showing a modified manner of supporting thedampening-roll.

Referring to\the drawings, the numeral 1 represents oneof the sideframes of the machine, two of said frames being employed and4 united insome suitable manner, as by tiebolts, (designated by 2,) each of saidside frames being slotted at 3 to receive the journal-boxes of thepressure, copying; and dampening rollers. These rollers are designatedas follows: 4 represents the copying roll, mounted inthe boxes 4 at thetop of the machine 5` 5, the combined pressure and drying ferredconstruction.

Fig. 5 is a sidev roll, cooperating with the roll 4; 6, the drying-rollin engagement with the roll 5, and 7 the dampening-roll, which may bemounted either in bearings of the journal-box 6', as shown by dottedlines in Fig-1, or in stationary bearings projecting from the'frame, asshown at 40, Fig. 6, this latter being the pre- The copying, pressure,and drying rollers are varranged in' the form lof a. three-high mill,and the dampeningroll 7 is of small diameter and is located at somedistance from the drying-roll6, said roll 7 being preferably mounted instationary bearings, as shown in Fig. 6.

The numeral 8 designates a reel adapted to receive a roll ofcopying-paper 9, from which the web or sheet is carried under thedampening-roller, threaded between the threehigh rollers, and advancedeither to the cutter or to the winding-reel, as hereinafter set forth.

The'numeral 10 designates the pan or tank for containing the dampeningfluid in which Y the roll 7, over which the paper is passed, is

partially immersed. This panor tank is provided with a series ofinclines or wedges 10', having flattened portions 102 resting upon therolls or ties 2. By virtue of this construction the tank 10 will beelevated as it is shoved into place beneath the rolls and will of coursebe lowered when withdrawn therefrom, asuitable handle 10X being providedfor the purpose of manipulating the tank.

To the journals of the upper roll 4 are attached eccentric portions 4',and a swinging bail or handle 11 is shown integral with one of saidportions and frictionally held on the eud of said roll. (See Fig. 6.)

Caps 12 are provided for secu ring the boxes 4" of the upper roll inplace, and these caps are fastened in position by ordinary screws orbolts 12', and each cap is chambered at 122 to receive a spiral spring90, said springs bearing against the boxes 4" and causing the rolls tobe held in contact under yielding pressure.-

The numeral 13 designates 'a reel composed of a barrel 13and rods 14,connected thereto by endQpieces 15. The axle of thisv reel is equippedwith a pulley or'similar device 16 of small diameter, .as shown moreclearly in Fig. 3, and this pulley is connected by a belt 17 with apulley 70 of larger size, clamped on.

the axle of the combined pressure and .drying IOO roller 5, as byascrew71. (Shown in Eig. 6.) Open bearings 80 are provided on the frame forthe reception of the axle of said reel, and it may be readily slippedinto place or withdrawn from said bearings. The barrel 13of the reel 13is grooved at its top, as at 18, to receive the longitudinal portion ofa paperclamp 19, the ends 2O of which are provided with suitable knobsor handles and are movable back and forth in perforations 21 in saidbody 13.

Projecting from the forward end of the frame of the machine areextensions 22, one of which is provided with a perforation 23 and theother with a rabbeted portion 24.- for a purpose hereinafter set forth.Mounted on these extensions 22 is the frame 25 of the paper-severing orpaper-cutting device, (designated in a general way by 26 and illustratedmore particularly in Fig. 2,) said frame being provided at one end withapin or lug 25', adapted to fit the perforations 23 in onerof theextensions 22 and at its other end with a A downwardly-extending lip252, fitting the rab- 6o be beted portion 24 of the other extension 22,a bolt or other fastening device 2 7 being employed to secure said framein position.

Rising from the frame 25 is a standard 28, to which is pivoted a lever29,`carrying on its under side a serrated knife or cutter 30, said leverbeing equipped with a handle 29 and perforated, as at 30', to receivethe stems or Shanks 31 of a yielding presser-foot 32, which is normallythrust below the knife or to the position shown Ain Fig. 2 by suitablesprings 33, surrounding the stems 3l. This presserfoot has peculiarclamping-faces consisting of straight portions 32' and inclined orbeveled portions 322, as shown in section at the right in Fig. 1, andthe base or frame 25 of the cutter is provided wi th side extensions253, having similar clamping-faces 25* and 25G to receive the impact ofsaid clampingfaces o n the presser-foot. The frame 25 is also providedwith a slot or kerf 34 for the reception of the cutter 30. -1

A removable table 35, uponwhieh the manuscript to be copied is placed,is mounted on the top of the machine and is provided with agroovedportion 35' for fitting over one of the cross ties or bolts 2, ble isheld in position. The paper strip or web 90 is fed from reel 9 in thedirection of the arrow under the dampening-roll 7 over the drying orwringing roller 6 and between said roller 6 and the pressure-roller 5and over and between the roller 5 and the copyingroller 4, and fromthence to the reel 13, upon which it is wound, or to the cutter, if saidreel omitted. The pressure of the rollers upon the strip may be nicelyregulated by manipulating the set-screws 95, bearing against thejournal-boxes of roll 6, (see Figs. '1, 5, and 6,) the heads of whichscrews are accessible through openings 96 in the frame, laid screwsbeing locked against movement by jam-nuts free end thereof by whichmeans said ta- 97 after they have been adjusted. The letters or othermanuscript to be copied are placed upon the table 35and are passedtherefrom with the written side down between the paper strip and thecopying-roller, and said roller having been thrown down by handle 11 andeccentrics 4 in the manner before described sueh matter will be fedbetween the pressure-roller and the copying-roller in an obvious manner.The rollers 4, 5, and 6, which are preferably made of rubber, are turnedby a suitable crank or other device 36, applied to the axle of thepressure-roller 5, as shown'in Fig. 5, and after the web or strip hasbeen threaded between 'said rolls the may be secured to the winding-reel13 by means of the clamp 19. As shown in Fig. 1, the relative sizes ofthe pulleys on the reel 13 and roller 5 are such that the reel 13 isdriven by the belt 17 slightly faster than the roller travels, wherebythe paper is kept taut and all danger of crimping or tearing the same isobv'iated, the belt 17 slipping when the tension on the strip becomestoo great.

If atany time it is desired to sever the copied matter directly from thestrip or web, the reel is removed from the open bearings 8O and the freeend of the sheet passed over the base of the cutting-frame 25. The lever26 is then depressed, and as it falls the presserfoot 32 comes incontact with the paper and the peculiar surfaces thereof clamp the sameto the base at two points on each side of the slot 31 and simultaneouslyslightly stretch the paper. Upon a further downward movement of thelever 36 the serrated or other form of knife 30 is forced throng-h thepresserfoot and into the slot 34 of the base-piece to sever the sheetfrom the webA of paper, and the paper being held taut in this manner theknife operates to sever the same with a clean cut.

By arranging the rolls and connecting one of them with the reel in themanner described the paper from the roll 9 on re'el 8 will be smoothlyand evenly fed between the rollers and will, as above stated, be heldsuliciently taut to prevent buckling..

As is obvious, thesheets of paper containing the copied the strip woundon the reel by severing the web at a point between the winding-reel 13and the rollers and carrying the free end thereof over the base 25 ofthecutter. When this is done, the belt 17 may be removed from pulley 16 orthe clamp-screw 71 'of pulley loosened, and the reel will then freelyrotate in its bearings as the web is' pulled therefrom. After the matterto be copied has portion of the strip or web between said rollers andthe reel 13, and this pressure may be relieved at any time by throwingthe handle 11 over to the left, and

IIO

thus turning the eccentrics 4', whereby all danger of iattcning theperipheries of they rolls is avoided.

While I have shown a belt as a convenient means for driving thereel 13from one of the rollers,yet the invention is not limited thereto, asother forms of gearing may be substituted for said belt.

By-the means shown and described the rollers can be so adjusted thatthey will bear upon each other with even and regular pressure.

By mounting the dampening-roller in stationary boxes, as shown in Fig.6, said roller is always maintained in the same position and is immersedto' a certain depth in the fluid in the pan or tank.

Having described my invention, what I claim, and desire to secure byLetters Patent,
